From 2a2349f0e21cb4de52917962185aaf1dd302ac5b Mon Sep 17 00:00:00 2001 From: Val Packett Date: Fri, 2 Jan 2026 04:07:48 -0300 Subject: [PATCH] ucm2: codecs: wcd937x: Use CLS_H_LOHIFI instead of CLS_H_ULP by default The ULP mode is too weak to drive headphones, causing distortion above 30-40% volume. Switch to LOHIFI as a more reasonable default.
